To all whom it may concern:

Be it known that 1, HENRY Cass, a citizen residing at Gloversyille,

York, have invented'a certain new and useful Improvement in Hill ed-LeafButtons, ofwhich the following is a description. This invention relatesto that class of buttons, commonly known as collar-buttons, which have ahead hinged to the post in such arallel with the post to pass it throughthe uttonhole and then turned back at right angles to the post, so as tostand crosswise of the buttonhole. This hinged head is also known as ahinged lea and this last-named term is herein used to designatethe part.

has been used to act upon the leaf and its post to holdthe leafin itstwo positions, and in several instancesthe post itself is both post andspring.

The invention consists of a hinged-leaf button having a leaf hinged to aspring and the spring and a casing therefor 'xed to a shoe againstrelative longitudinal movement, all as I will now proceed to-moreparticularly set. 'forth and finally claim.

In the accompanying drawings, illustrating the invention, in the severalfi ures of which like parts are similarl designated, Figure 1 isanelevation with t e hinged leaf turned up parallel with the post. Fig. 2is a Fig. 4 is aview similar Fig. 6 is a l n plate. of the liinged leaf.The shoe 1 may I tion, and upon it is erected a tubular casing 2longitudinal section taken at right angles to the view shown in Fig. 1,but with the hinged leaf at right angles to the post. Fig. 3 isahorizontal section taken in the lane of line A B, Fig. 2, and lookingtowar the hinged leaf. to Fig. 1, but with the hinged leaf about midwaybetween its hori zontal and its vertical positions. Fig. 5 is aperspective view of the springdetached. view of thetwo-part pivotbe ofany usual construe of any suitable shape in cross-section. Withspringhas two arms connects 7. The spring is placed lar casing so that itsbase ring 3. This by an integral base 4, and the opposite ends of thesearms in this casing is placed the s are providedwith the projecting ears5, which are erforated transversely at 6 and have theaterally-projecting straight-ed ed cams within t e tubu- 4 is in thebottom of the casing next to the shoe, and than the 'ull, clear, andexact.

ceive the ears 5 of A spring metal of the casing is set in or indentedover this base, as at 8, so as to hold the spring in place within thetubular casing without inipairing its spring action. Obviously thespring is made to act by a movement of the spring-arms toward and fromone another.

The head or hinged leaf iscomposed, preferably, ofa cap-piece 9 and apivot-plate 10, which latter is made in halves, as shown moreparticularly in Figs. 3 and 6, and these halves are cut away, as at 11and 12, to rethe spring, and they are also made with the pintles 13,which enter the holes 6 in the ears of the s ring, .and thereby serve asivots for the leaf.

The parts of t e plate 1.0 having their pin tles inserted in the holes 6are brought together and secured within the capiece 9, and thus the heador leaf is hinge to the spring. The outward or diverging pressure of thespring-arms, which is the normal set v of the spring,

is sufficient to hold the hinged leaf in position; but to insure suchposition the straight edges 14 of the cams 7 when the hinged leaf is inthe horizontal position, as shown in Fig. .2, engage the inner edges ofthe pivot-plate next to the openings 11, and thus lock the leaf in thatposition. larly, when the hinged leaf is turned up into the positionshown in Fig. 1 the straight edges 15 of the cams engage the outer edgesof the pivot-plate 10 next to the openings and lock the said hinged leafin that position To put the hinged leaf in either position, some littleforce is. required to overcome the spring, and it will be observed uponcomparing Figs. 1 and 4 that in going the vertical position or reverselythe arms of the sprin are caused to approach, the cams meanwhi e ridingupon the vertical edges of the opening. I

y are allowed perfectfreedom of movement m the operation of the hingedleaf, and at the from the horizontal to the use of the casing2 thespring-arms same time the spring-post is entirely protected from wearand entanglement or disarrangemen't.

In this-construction the spring is made anlar or of angular stock and atconsiderably ess cost than if round and may be secured in place by meansof its angular base very much more readily than if stock ofcircularcross sectionwerau I have thus described the principle of myinvention and the best mode 111 which I have contemplated applying thatprinciple; but it is obvious that there are numerous equivalents of thisprinciple.

VVh'at I claim i's- 1. A button, having a hinged leaf, a spring uponwhich the hinged leaf is pivoted, a casingfor the said spring and a shoeupon which the spring and easing are fixed against relative lon itudinalmovement.

2. A hutton, having a spring, a leaf pro vided with a two-part platecontainin pivots engaging the spring, a casing for t e said spring and ashoe upon which the spring and:

casing are fixed against relativelongitudinal movement.

3. A button, having a spring provided 1 [pivot-ears and locking-cams onsaid ears, a

eaf having a pivot-plate pivoted to said ears and adapted to engage withthe earns, a cas .ing for said spring and a shoe upon which the springand easing are fixed against relative" longitudinal movement. p 4'. Abutton, having a, hinged leaf, a spring upon which the hinged leaf ispivoted, a casing for the said spring and Within which the spring is,fixed against longitudinal movement and a shoe upon which the spring andeasing are fixed against relative longitudinal movement.

5. A button, having a shoe, a casing free ends of said arms having earsand cams and'a leaf pivotally connected to said ears and adapted tocooperate With said cams so as to be capable of-being held. thereby ina-position at right angles to the casing and in a position substantiallyparallel to the casing.
